Moreover, the film may be made from a composition that has a contraction value of from about 30% to about 160%. The film thickness is from about 5 microns to about 50 microns, preferably from about 10 microns to about 40 microns, when applied. The standard deviation of the film over the area covered is less than about 30, preferably less than about 25. ## Claims ### Claim 1 A skin smoothing composition that comprises sodium silicate, polyvalent silicate which is a hydrated magnesium aluminum silicate, and water carrier, the skin smoothing composition forms a film having a thickness of from about 5 microns to about 50 microns, when applied to an area of skin having wrinkles the skin smoothing composition comprising: a) from about 0.5 to about 4% sodium silicate as measured by silica content (Si02); b) from about 0.1% to about 4.0% of a polyvalent silicate which is a hydrated magnesium aluminum silicate which is stable in compositions having a pH greater than 10; c) from about 10 to 98% water; and d) from about 1% to about 20% of a plasticizer; and wherein the ratio of the weight of the sodium silicate to the polyvalent silicate is from about 1.0 to about 3.0 and the ratio of total silicate to plasticizer is equal to or less than 1.8 and the composition is in the form of a gel or oil-in-water emulsion; and wherein the pH of the composition is greater than 10. ### Claim 2 (depends on 1) The skin smoothing composition of claim 1, wherein the polyvalent silicate is a silicate clay selected from the group consisting of bentonite, laponite, smectite, kaolinite and mixtures thereof. ### Claim 3 (depends on 1) The skin smoothing composition of claim 1, wherein the plasticizer is an alkyl monoglycol or di-glycol. ### Claim 4 (depends on 1) The skin smoothing composition of claim 1, wherein the plasticizer structure contains 3 to 5 carbon atoms. ### Claim 5 (depends on 1) The skin smoothing composition of claim 1, wherein the plasticizer is propylene glycol. ### Claim 6 (depends on 1) The skin smoothing composition of claim 1, wherein the skin smoothing composition further comprises at least one polysaccharide thickener. ### Claim 7 (depends on 6) The skin smoothing composition of claim 6, wherein the polysaccharide thickener is xanthan gum. ### Claim 8 (depends on 1) The skin smoothing composition of claim 1, wherein the skin smoothing composition further comprises from about 0.001% to about 5% of a particulate material selected from the group consisting of colored and uncolored pigments, interference pigments, inorganic powders, organic powders, composite powders, optical brightener particles, and mixtures thereof. ### Claim 9 (depends on 1) The skin smoothing composition of claim 1, wherein the skin smoothing composition further comprises at least one skin care active. ### Claim 10 (depends on 9) The skin smoothing composition of claim 9, wherein the skin care active is selected from the group consisting of vitamin B compounds, vitamin C compounds, vitamin E compounds, peptides, sugar amines, natural botanical extract, oil control agents, skin lightening agents, and mixtures thereof. ### Claim 11 (depends on 9) The skin smoothing composition of claim 9, wherein the skin care active is selected from the group consisting of niacinamide, palmitoyl-lysine-threonine, palmitoyl-lysine-threonine-threonine-lysine-serine, N-acetyl-D-glucosamine, salicylic acid, dehydroacetic acid, sodium dehydroacetate, hexamidine compounds, and mixtures thereof.
